(Sehgal, 1996) reported that systematic study of soils provided an opportunity to understand the soil health to accelerate the land use planning in area of interest. In this context, soil pH, EC and OC are important parameters that affect plant growth. Amacher et al., (2007) reported that pH is used as an indicator of the acidity or alkalinity presence in soils which controls the mobility and the availability of soil nutrients. If a soil is too sour or too sweet, plants cannot take up International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 9 (2020) Journal homepage: http://www.ijcmas.com Soil pH, EC and Organic Carbon are the essential parameters used as the primary level health status of the soils. In this context, detailed study over soil pH, EC and OC was done for different panchayats of Sabour block of Bhagalpur district. 80 composite surface soil samples (0-15cm) using GPS receiver from different location of fourteen Panchayats of Sabour block were collected during the months of May and June, 2019. The sample points were recorded in GPS receiver to find out the coordinate(s) and used to record the data of soil parameters viz. pH, EC and organic carbon in excel file towards the analysis of spatial variability and correlation using interpolation (IDW) technique. It was observed that soil pH under 52.5 % soil samples was as neutral and 41.25% soil samples were slightly alkaline in nature. However, the range of EC was under in non-saline category and varies from 0.10 to 0.36 dSm -1 . While organic carbon ranged from 0.15-0.49 % with a mean value of 0.33 % which was positively correlated with soil pH and EC. Normal EC indicated the safe for all agricultural crops. However, organic carbon was low in all the panchayats which is needed to be management practices.
